In the 40 or so years that people have been developing software, a range of common tasks, such as sorting and searching, have been identified and a body of knowledge has been accumulated about how these tasks are best carried out. This knowledge usually consists of various ways of structuring the data, a range of different algorithms, and performance analysis that enables a designer to chose the algorithm and data structure most appropriate to the circumstances of the system, and to predict how the system will perform.
This module introduces students to this body of knowledge and sets it into the context of modern software design and structuring techniques.
The aims of this module are to:
On successful completion of the module, students should:
Course Overview -
Time/space complexity. Issues of correctness as they relate to the definition of ADTs. Abstraction and encapsulation. Notations for describing ADTs. Review of Java support for their implementation: packages, exceptions and interfaces.
Further Design and Implementation of Computer Programs -
Programming language facilities to support more advanced data structures and the development of larger, more reusable software. Linear data structures: stacks, queues and lists of objects, implemented using arrays and utilising interfaces.
Dynamic Storage Allocation -
Unbounded data structures and a comparison with their bounded equivalents. Implementation of dynamic storage allocation in run-time systems; 'heap creep'.
Object-Oriented Techniques -
Object-oriented analysis and design. The Unified Modelling Language (UML). The Unified Process, a recipe for developing UML diagrams during object oriented analysis and design.
Introduction to Complexity -
OO notation, growth rates. Measurement of execution time of program examples and the estimation of their time complexity. Examples of time/space trade-offs.
Storing and Retrieving Data by Key From Internal Storage -
Binary search trees, 2-3 trees. How the characteristics of the problem (data volumes, volatility and relative frequency of the different operations) affect the choice of data structure.
Storing and Retrieving Data by Key from External Storage -
Performance issues. Hashing and B-tree organisations. The Hashable class in Java.
Quicksort, Mergesort and Selection Sort and their time complexities.
Weighted, directed graphs. Shortest path algorithms, breadth first and depth first searching. Minimum spanning trees and topological sorting.
